The present invention relates'to vending mechanism "and provides yanattachment" to be associated' with a fluid Idispensirrg pump such asgenerally provildedftor'gasoline stations so that upon depositingacoinot predetermined denominate value given'ainount of fuel or oil may zbeobtained; 4

Corresponding and like parts are referred to in the followingdescription and designated in the several views ot the drawings by likereference characters.

The numeral denotes a suitable housing for enclosing the operatingparts. A transverse shaft 11 is journaled in opposite sides ot thehousing 10 and projects at one end to which is iitted a gear Wheel 12which 1s arranged to cooperate with the pump operating rack 13. A detentwheel 14 and a gear wheel 15 are mounted upon the shaft 11 and aresecured thereto so as to rotate therewith. A double ended dog or detent16 coacts at its respective ends 16a and 16h with the detent wheel 14 toprevent rotation thereof and operation of the vending mechanism, the end16b being connected by means of a link 17 with one arm of a lever 18 theother arm of said lever being disposed to coact with a rack bar 19, theteeth of which are adapted to mesh with the teeth of the gear Wheel 15,said rack bar being held in predetermined position by rollers 20 whichare adjustable to maintain proper meshing relation ot the teeth of therack bar 19 and gear Wheel 15. A lat-ch 21 is adapted to engage 011e endof the Referring lever-18 so as` tdholdthe detent 16 in neutral positionas indicated by the dotted lines in Figure t2,"whereby the mechanism maybe operatedat'will without necessitating the deposition of a'coin.- Arod22 at one side of the rack bar 19 and connected thereto is providedwithan upper stop23 and a lower stop 24,`said 'stops being adjustable. Theupper 'stop 23 isadapted to engage one end oi the lever18 and thelowersto'p' 24 is adapted to ei'igag'e 'one end'of a lever 25 which isconnect'ed by means of aY link 26 with an arm 2T,

which'in turnis connected by means of a link 28 with acutfott 29 adaptedwhen lowered to 'extend aero'ssthe entrance of a coin chute 30. A spring31`normally tends to close the cut oit'29: A passage 32opens into a coinbox 33"'and' the coin chute 30 is in communication therewith andthis'passage receives a plunger 34 which is normally held'V at the limitof-its outward movement by means ot' a spring 35.

A; retarder 36 normally projects into the passage 32 and is adjustablyconnected to the detent 16 and operates to retard the forward movementof a coin 37 when entering the passage after leaving the coin chute 30.

The operation of the machine is as tot lows:

Normally the rack bars 13 and 19 are in i lowered position and the cutoli" 29 is held elevated by the stop 24 engaging the adjacent end of thelever 25. Operation ot' the mechanism is prevented by the detent 16 atend 16" engaging a tooth ot the detent wheel 14. Upon depositing a coin37 in the chute 30 it is received in the passage 32, its forwardmovement being' checked by the retarder 36. The plunger 34 being pressedinwardly causes the coin 37 to ride under the retarder 36 with theresult that the detent 16 at end 16b is moved away trom the teeth ot'the detent wheel 14 and is held in such position by means of a spring 38mounted upon a stem 39 consisting ot separate sections 39 and 39"connected by said spring, the latter section being pivoted at one end tothe housing as indicated at 40 and the former being pivoted at 40 to thestem 41 of the detent 16. lVhen the stems 39 and 41 are in line, thedetent is in neutral position or upon the dead center and a slightmovement in either direction causes the spring 38 to react and throw thedetent end 16 or 1Gb into engagement with the detent wheel 14.
